Introduction

SlideWiki
aims to exploit the wisdom, creativity and productivity of the crowd for the
creation of rich, deep-semantically structured E-Learning content
. Users can create and collaborate on educational slides, diagrams, assessments and arrange slides in presentations. Presentations can be organized hierarchically, so as to structure them reasonably according to their content.

SlideWiki empowers communities of instructors,
teachers, lecturers, academics to create, share and re-use sophisticated
educational content in a truly collaborative way. In addition to
importing PowerPoint presentations, it supports authoring of interactive
online slides using HTML and LaTeX. Slides and their containers (called decks), are versioned, thereby enabling change tracking. Users can create
their own themes on top of existing themes or re-use other's themes.

Translation

Presentations can be automatically translated into 54 languages and then
edited
and
saved
independently from the original.

After the original deck was changed, the translation deck start to have notification about that. There is the possibility to
compare
the revisions and to
update
the translation in accordance with changes.

How to translate your deck

Make sure that you are logged in SlideWiki

Select a deck or subdeck in the tree

Open the list of existing translations in the top-right corner (see screenshot below)

You can open existing translations of the deck by clicking on one of the languages

If the desired language is not available in the list or if the translation is outdated, use the translate button at the bottom of the list

SlideWiki will redirect you to the translated deck. However, the translation will not be ready momentarily, as it takes time to manage the translation process. Please, wait a few minutes and reload the page with the translated deck or return to it later.

After the translation is completed, you can revise it

Questionnaires

SlideWiki allows to
attach multiple-choice questions to each individual slide
. This adds the following functionality:

if slides are copied or reused, so are the questions attached to them

For each presentation the learner can start a
self-assessment test, which launches a multiple-choice test composed of all or a selection of questions attached to slides of the presentation

Such questionnaires are
structured
according to the structure of the presentation, which allows to apply
module-based score
systems without additional teacher's work.

SlideWiki allows to score the results with 5
different algorithms, including a novel one.

Import & Export

SlideWiki allows to import & export presentations from:

Powerpoint (.pptx format, import only)

Currently, only raster images are imported from Powerpoint, but import of vector graphic (converted to SVG) is planned.
